I predict 7 draws, 3 Kasparov, and 2 Karpov. = 6.5 - 5.5
KASPAROV_KARPOV PREDICTION CONTEST!!!
Yes, and whoever calls "next game" gets to play the winner in chess and
basketball. OK, that part I just made up. Go to Sonofpearl's blog for more information.

The ghost of Fischer will rise from under the table, challenge them both to a new three-handed 960-type variant, timed with an even more fiendish 3 plunger clock. Fischer 12, Kasparov 0, Karpov 0.

Kasparov is going to kick Karpov's backside. Karpov's recent tournement results says it all ;)
I'm afraid that is dead-on accurate. Karpov's results against younger players have been quite disappointing. Probably the age gap is finally going to sink Karpov into retirement...but who knows? After all, they do know each other a whole lot...AND Kasparov's been away from professional chess for quite a while - I reckon coaching Carlsen doesn't qualify as match preparation.
So...maybe Kasparov 6,5 - Karpov 5,5.
Let's have a contest just for fun to see who predicts the outcome of the
Kasparov-Karpov Rematch. I predict Kasparov 4 wins Karpov 3 wins 5 draws.
---Final Score: 6.5-5.5---
What do you think? This will be exciting!
